Giorgio Moroder — Italian Producer born on April 26, 1940,

Giovanni Giorgio Moroder is an Italian record producer, songwriter, performer and DJ. Moroder is frequently credited with pioneering synth disco and electronic music... (wikipedia)

Phil Ramone is very special. Barbra Streisand or Diana Ross... they are the best.
It is at least 10 times more difficult to get a good synthesiser sound than on an acoustic instrument.
One of the most interesting things, at least for me, are the soundtracks for 'The Social Network' and 'Drive.' Basically, it's what I did in 'American Gigolo.' I could have done the music for those movies blindfolded. And one of them won an Oscar, and the other is this massive soundtrack.
Once you free your mind about a concept of music and harmony being correct, you can do whatever you want.
A producer is always behind the scenes, even more in the movies - nobody sees you. I didn't even meet most of the actors. When I worked on 'Top Gun,' I never met Tom Cruise. You were always in the background.
